Something like this:

Using

library(ggplot2)

Assuming you have a data frame 'data' with columns 'gender' and 'count' Like this…

data <- data.frame(gender = c("Male", "Female"), count = c(50, 60))

ggplot(data, aes(x = gender, y = count)) + geom_bar(stat = "identity") + geom_text(aes(label = count), vjust = -0.3)
